Description

Technical Field

[0001] This utility model relates to the technical field of wire rope leakage magnetic field detection equipment, specifically to an online detection device for mining wire ropes. Background Technology

[0002] The information disclosed in the background section of this utility model is intended only to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0003] Mining wire ropes often experience dynamic angle changes during underground operation due to factors such as the winding characteristics of the hoist drum, the deviation of the guide wheel, and the sag of the wire rope itself. Existing magnetic flux leakage detection devices use a fixed installation structure, which has the following core defects:

[0004] Coaxiality deviation leads to detection failure: The fixed magnetic flux leakage detection body and the angle-offset steel wire rope form a coaxiality deviation, resulting in uneven gap between the sensor and the surface of the steel wire rope, the appearance of unsaturated areas in the magnetization area, large fluctuations in the amplitude of the magnetic flux leakage signal, and a high rate of missed detection due to broken wires.

[0005] Angle adjustment is cumbersome: if the angle of the wire rope is permanently offset, the entire detection device needs to be disassembled and re-drilled and installed. Each adjustment takes a long time, interrupts production and has high maintenance costs.

[0006] To address the aforementioned issues, there is an urgent need to design a multi-dimensional adjustable and real-time adaptable online detection device for mining steel wire ropes, enabling the leakage magnetic field detection body to dynamically adjust with changes in the angle of the steel wire rope, thereby ensuring detection accuracy. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model proposes an online detection device for mining wire ropes, aiming to solve the problem that existing wire rope magnetic leakage detection devices are difficult to adapt to changes in wire rope angle, leading to detection failure.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A mining wire rope online detection device includes a base, and a wire rope magnetic flux leakage detection body is installed on the top of the base;

[0010] A rotating cylinder seat is rotatably installed inside the base. The upper end of the rotating cylinder seat is provided with a lifting cavity, and the lower end is provided with a rotating drive cavity. A lifting platform that can slide up and down is installed inside the lifting cavity. The lifting platform is driven by a lifting drive device. An internal gear ring is provided on the inner side wall of the rotating drive cavity. The internal gear ring is in transmission cooperation with the rotating drive gear. The rotating drive gear is driven by a rotating drive device, which is installed and fixed on the base.

[0011] A central column is fixedly installed at the center of the lifting platform, and an installation platform is installed at the top of the central column with a limiting hinge. The wire rope magnetic leakage detection body is installed and fixed on the installation platform. The bottom of the installation platform is also limited and hinged to the telescopic end of the pitch adjustment drive device, and the other end of the pitch adjustment drive device is limited and hinged to the lifting platform.

[0012] Preferably, a fixed seat is provided at the bottom of the central column, and a limiting hinge seat is provided on the fixed seat for limiting hinge installation of the bottom end of the pitch adjustment drive device.

[0013] Preferably, the lifting platform has a cylindrical cap structure, the side wall of the lifting platform is provided with a slider, and the inner side wall of the lifting cavity is provided with a groove adapted to the slider.

[0014] Preferably, a rotary assembly is fitted between the base and the rotating cylinder seat.

[0015] Preferably, the lifting chamber and the rotation drive chamber in the rotating cylinder are separated by a partition, and the lifting drive device is mounted and fixed on the partition.

[0016] Preferably, an end cap is detachably installed and fixed at the bottom of the base, and the rotation drive device is driven and fixed on the end cap.

[0017] This utility model has at least the following beneficial effects:

[0018] In this invention, a multi-dimensional adjustment structure effectively solves the coaxiality deviation problem caused by dynamic changes in the angle of the steel wire rope in existing fixed-installation testing devices. The multi-dimensional adjustment includes the following adjustments:

[0019] Horizontal angle adjustment: The rotary component between the base and the rotating cylinder provides stable rotation support for the rotating cylinder. The rotary drive device drives the rotary drive gear to mesh with the internal gear ring on the inner side of the rotating cylinder, which can drive the rotating cylinder to rotate around the base axis, thereby realizing the angle adjustment of the wire rope leakage magnetic detection body in the horizontal plane.

[0020] Pitch angle adjustment: The mounting platform is connected to the top of the central column through a limiting hinge. The pitch adjustment drive device is respectively limited hinged to the lifting platform and the mounting platform at both ends, which can drive the mounting platform to rotate around the hinge axis to realize the pitch angle adjustment of the detection body.

[0021] Height adjustment: The lifting platform slides in conjunction with the inner slide groove of the lifting cavity. The lifting drive device is fixed to the partition and drives the lifting platform to slide up and down along the lifting cavity, which can drive the upper module and its detection body to rise and fall synchronously; ensuring that the detection body is always at the detection height that matches the wire rope, avoiding the impact of height deviation on the detection effect;

[0022] The aforementioned multi-dimensional adjustment and synergistic effect can adapt in real time to the angle changes of the wire rope caused by drum winding, guide wheel deviation, and self-weight sag, ensuring that the leakage magnetic field detection body and the wire rope detection section can always maintain a coaxial state, eliminating the problem of uneven gap between the sensor and the wire rope surface, avoiding the appearance of unsaturated areas in the magnetization region, significantly reducing the amplitude fluctuation of the leakage magnetic field signal, reducing the rate of missed detection of broken wires, and significantly improving the detection accuracy. It can dynamically adapt to the angle of the wire rope in multiple dimensions, improve the detection accuracy, and is modular for easy assembly and maintenance, making it suitable for online detection of mining wire ropes.

[0023] In addition, this utility model achieves modular integration, significantly improving the ease of installation and maintenance of the device, as detailed below:

[0024] The device is divided into two modules: the upper module is centered on the central column and integrates the main body of the wire rope magnetic flux leakage detection, the mounting platform, the pitch adjustment drive device and the fixed base; the lower module is centered on the base and integrates the rotating cylinder base, the lifting platform, the lifting drive device, the rotation drive device and the end cover; the two modules can be prefabricated and assembled separately and then connected for installation, simplifying the on-site installation process.

[0025] The base features a detachable end cover design, with the rotation drive device fixed to the end cover. Removing the end cover allows for easy inspection or replacement of the rotation drive device. The lifting chamber and the rotation drive chamber are separated by a partition, which protects the lifting drive device from contamination and facilitates separate maintenance of the lifting components.

[0026] The modular design described above eliminates the need for complete disassembly of the device to repair or replace components. Instead, operations can be performed on the faulty module or component, reducing maintenance difficulty, spare parts replacement costs, and improving the overall operational efficiency of the device throughout its lifecycle.

[0031] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Figures 1 to 2 An online detection device for mining wire ropes is presented, including a base 100. A wire rope magnetic leakage detection body 610 is installed on the base 100. The wire rope magnetic leakage detection body 610 is the main device for detecting the magnetic leakage of wire ropes. This is a very mature technology and existing technology can be used. Those skilled in the art should understand that it is not the design point of this application and will not be elaborated on here.

[0033] A rotating cylinder seat 300 is rotatably mounted inside the base 100. A rotary assembly 200 is fitted between the base 100 and the rotating cylinder seat 300. The rotary assembly 200 can be a bearing. The upper end of the rotating cylinder seat 300 is provided with a lifting cavity, and the lower end is provided with a rotating drive cavity 310. A vertically sliding lifting platform 400 is installed inside the lifting cavity. The lifting platform 400 is driven by a lifting drive device 420. In this embodiment, the lifting drive device 420 is an electric cylinder or a hydraulic cylinder. An internal gear ring 330 is provided on the inner sidewall of the rotating drive cavity 310. The internal gear ring 330 is in transmission engagement with a rotating drive gear 340. The rotating drive gear 340 is driven by a rotating drive device 341.

[0034] A central column 500 is fixedly installed at the center of the lifting platform 400. A mounting platform 600 is hinged to the top of the central column 500. The "limiting connection installation" described in this application refers to the presence of back plates on both sides at the hinge. These back plates restrict the moving parts from swinging to the left and right, allowing only rotation around the hinge axis. The subsequent "limiting connection installation" follows the same principle. The wire rope magnetic leakage detection body 610 is fixedly installed on the mounting platform 600. The bottom of the mounting platform 600 is also hinged to the telescopic end of a pitch adjustment drive device, and the other end of the pitch adjustment drive device is hinged to the lifting platform 400.

[0035] To facilitate installation and enhance modularity, a fixed base is provided at the bottom of the central column 500. This fixed base is equipped with a limiting hinge seat for the bottom end of the pitch adjustment drive device. Thus, the central column 500, the wire rope magnetic leakage detection body 610, and the pitch adjustment drive device can all be integrated and installed on the fixed base, forming the upper module. The base 100 and its internal rotating cylinder seat 300, lifting platform 400, lifting drive device 420, and rotation drive device 341 constitute the lower module, making the entire device divided into upper and lower modules.

[0036] The specific structure of the lifting platform 400 is a cylindrical cap structure, and its sliding installation can be as follows: the side wall of the lifting platform 400 is provided with a slider 410, and the inner side wall of the lifting cavity is provided with a sliding groove adapted to the slider 410.

[0037] The specific installation of the lifting drive device 420 and the rotation drive device 341 can be as follows: the lifting cavity and the rotation drive cavity 310 in the rotating cylinder seat 300 are separated by a partition, and the lifting drive device 420 is installed and fixed on the partition.

[0038] The bottom end of the base 100 is detachably and fixedly fitted with an end cover 320, and the rotation drive device 341 is driven and fixedly fitted onto the end cover 320.
